Beschreibung
The XR17V3581 (V358) is a single chip 8-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The V358 serves as a single lane PCIe bridge to 8 indepedent enhanced 16550 compatible UARTs. The V358 is compliant to PCIe 2.0 Gen 1 (2.5GT/s).In addition to the UART channels, the V358 has 16 multi-purpose I/Os (MPIOs), a 16-bit general purpose counter/timer and a global interrupt status register to optimize interrupt servicing.Each UART of the V358 has many enhanced features such as the 256-bytes TX and RX FIFOs, programmable Fractional Baud Rate Generator, Automatic Hardware or Software Flow Control, Auto RS-485 Half-Duplex Direction Control, programmable TX and RX FIFO Trigger Levels, TX and RX FIFO Level Counters, infrared mode, and data rates up to 25Mbps. The V358 is available in a 176-pin FPBGA package (13 x 13 mm).
